## What does a pendulum suspension spring do?

The clock pendulum suspension spring is the short spring steel part on the very top of the pendulum assembly. Its purpose is to suspend the leader and pendulum in the air.

## Why does the pendulum stop on my grandfather clock?

The reason a clock pendulum often stops swinging, after being moved, is because the clock case now leans at a slightly different angle then it did at its former location. A clock is “in beat” when the tick and the tock are evenly spaced.

Why do old clocks have pendulums?

The advantage of a pendulum for timekeeping is that it is a harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. Pendulum clocks are now kept mostly for their decorative and antique value. Pendulum clocks must be stationary to operate.

### Why pendulum of clock does not stop?

If there were no friction or drag (air resistance), a pendulum would keep on moving forever. In reality, each swing sees friction and drag steal a bit more energy from the pendulum and it gradually comes to a halt. But even as it slows down, it keeps time.

### Why won’t My grandfather clock stay running?

Your clock needs to have an even “tick”. If the tick sounds comparable to a guy walking with a limp, it won’t run. The pendulum needs to travel an EVEN distance after each tick. If it doesn’t, it will stop.

What does RA mean on a clock pendulum?

The R A on the pendulum stands for: retard/advance. It is a common pendulum bob, used by many manufacturers, worldwide. As a rule of thumb, the thread on rating nut is designed so that one full turn changes the clock about 2 minutes per week.

#### How do you fix a grandfather clock?

Use your free hand to turn the minute hand of the grandfather clock to the correct chiming time. For example, if the clock had chimed at 12:10, instead of 12:15, the hand must be turned forward five minutes. Turn the hand right-side up, and place it back on the shaft of the grandfather clock.

#### Why does my grandfather clock keep stopping?

Grandfather clock keeps stopping. if the clock is on a timber or tile floor then check to make sure the case cannot rock, because that can cause the weights to swing in sympathy with the pendulum and stop the clock. anyway, it make no difference is the case is not perfectly upright, the beat can be set to where ever the clock is standing.

Why did the pendulum stop swinging?

When we swing a pendulam, it swings back and forth but eventually it stops. This is due friction with air. It is also because the kinetic energy released by the pendulam is dissipated into the air.
